If you know the names of the remaining nine students in the spelling bee, what is the probability of randomly selecting an order and getting the order that is used in the spelling bee?

1 / 362880

Step-by-step explanation:

There are 9 possible names that could be first.

After that, there are 8 possible names that could be second.

After that, there are 7 possible names that could be third.

So on and so forth.

So the number of permutations is:

9×8×7×6×... = 9! = 362880

The probability of randomly selecting the one order used in the spelling bee is therefore:

P = 1 / 362880

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
